I just received my ESP8266 module, the one with the 2*4 pin header on the side. I am also using a CP2102 based USB-serial dongle. Supplying the 3.3V from a separate power module.

When I power it up I can see the following message in Putty (9600bps 8N1):

Code: Select all[Vendor:www.ai-thinker.com Version:0.9.2.4]



ready

This tells me that the serial communication is set up correctly. (Right?)

The wifi part is also, OK, I can connect to the wifi network it creates.

BUT: it doesn't respond to any AT command I send to it. The blue LED flashes as I type in the terminal window (Putty), but it wouldn't respond to it when I press Enter.

Any idea what could be wrong? Could it be a faulty module? Do I miss some special setting in Putty?

Any pointers are appreciated!!!

Can you point me to a specific firmware I could try?
Cheers!
